TO ALL AWHOM IT MAYCONOERN:

Be it known that I, WILLIAM F. GOODWIN, of East New York, county of Kings, and State of New York, have invented a new and-useful Improvement in Hnrvesters or harvester-gearing; andIdo hereby declare the following 'to he a full, clear, and exact description of the same, reference being had to the accompanying drawings, in wliichl Figure 1 is a side elevation of my improved gearing, shown applied to the main drive-Wheel axle pf a .harvesting-machine.

Figure 2 is a transverse section ofthe same.

Figure 3 is a view of the tubular sleeve, pinions, transmitting-wheel, and arms detached.

Figure 4 is a detached view ofthe tubular sleeve, its fixed arm, and trausmittingwheel mounted thereon; and

Figure 5 is a detached view of the secondary arm, its pinion, and transmitting-wheel.

Siuiilarkletters of reference denote corresponding parts in all the figures.

My invention consists in a novel arrangement of p inions and transmitting-wheels relative to thernain or 'thriving-axle of the machine, and within an internnlly-coggeddrum, either revolving or stationary, whereby `the required number of revolutions of the crank-shaft, which operates 4the cutters, is obtained, as hereinafter explained.

In the accompanying drawings, A represents the main drive-wheel axle of a harvesting-machine, and B one of the driving and carrying-wheels, mounted thereon, and connected to lthe axle by means of backing ratchets, or in any usual or desired manner. C'is :a tongue-plate, which, in this instance is represented as 4attached to or formed in one piece, with a tubular sleeve, D, mounted on the axle A, in such manner as to ailow the latter to revolve freely therein. E is an internallycogged drum or wheel, representedas keyed or otherwise' rmly attached to theaxle, so as to revolve therewith, but which may, if preferred, be attached to one of the driving-wheels instead ofthe axle. F is an arm formed upon or firmly attached to the sleeve D, and provided with a stationary stud or pivot-shaft f, arranged in line parallel with the main axle, upon which piaf is mounted a. transmitting-wheel, G, arranged to mesh Awith the internally'cogged drum E, and with a tubular pinion,- H, on sleeve D. The pinion H ismounted loosely on the sleeve D, iu such manner as to turn freely thereon, an'd has secured to it an arm, F', which in turn is provided with a fixed stud, carrying a second transmitting-wheel, G', meshing with the internally-cogged drum E, and with a second tubular pinion, H', on the tubular sleeve D. This second pinion H has attached to or east withit` a bevelwheel or pinion, I, from which motion is imparted to a bevel-pinion on the crank-shaft, which drives the cutters, in a manner that will be readily understood.

i In the construction described and shown, the transmitting-wheelG is held in position bythe arm F,

attached to sleeve D, and does not revolve around the axle, but is revolved on the studf, and turning in the same direction with the drum E, causes the pinion H and its arm F', carrying the transmitting-'wheel G,'to revolve in a reverse direction to the drum. The drum being provided with (for theA purpose of illustration) 'say fortyeight teeth, and the pinion II with twelve, four revolutions of the pinion are produced for each revo# lution of the drum, and the pinion and its arm, revolving in a reverse direction to the drum, and making four revolutions for each revolution of the drum, the transmitting-wheel G' meshing with the drum, is caused to make a greater number of revolutions than could be obtained if the drum and transmitting-wheel did not revolve in opposite directionsfThe intermediate or transmitting-pinion G being in gear with the secondary pinion H', causes said pinion tomake twenty-four revolutions to one ot' the drum E, instead of sixteen, which would be the number of its revolutions if the drum E did not revolve around its shaft in an opposite direction to the movement of the seconda-ry arm and its transmitting-wheel, one-third of the whole number of revolutions made by the pinion H being thus obtained without additional gearing; in other words, with one-third less gearing than the same number of revolutions can hepbtained by any other known arrangement. Thus, when the drum has forty-eight teeth, and the pinions twelve cach, the number of revolutions ofthe pinionsfor one revolution of the drum will he as follows, viz: The rst pinion, H, makes four revolutions to one of thedrum, while the second pinion, H', makes twenty-four revolutions to four of .pinion H, and one of the drum E. The/same result van! 2 will be attained if the first arm, F, is keyed to the axle or shaft, .so as to revolve therewith, whilethe drum is attached to the machine-frame and held stationary. In this case,'the pnions-H I-Iland' arm F may be mounted directly on the axle instead of on the tubular sleeve. l-The sleeve, instead of being formed on the tongue-plate7 may form a part of the vibrating frame which; carries the cutters and crank-shaft, or said cutter-framev may be armed with sleeves, working on bearings on vsleeve D, in such manner as to `give to the frane. or frames a. concentric arrangement relative to theentire driving-gearing, thereby avoiding all possibility ot' cramping the gearing.

. If preferred, the arms F F may be extended upon opposite sides of the axle, and'armed with two transmittingwheels, one upon each bran'eli, gearing into'the drum upon opposite sides, and in-to the common pinion H or I-I, thereby giving additional strength to the structure.

The arrangement of gearing described is s-uch as to give tothe machines. compact form, rendering unnecessary any frame or framework, except such as is required to lsupport and carry forward the cutting-apparatus and its appendages, the entire gearing beingr arranged upon or around and supported by a common axle. It is particularly designed for the purpose of driving the cutters, the motion being such asto adapt it peculiarly thereto, but it may be applied to any of the operations pertaining to harvesting such as operating the rake, reel,'or binding-mechanism, as described.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, as an improvement .in harvesting-machines, is--v l. The' arrangement of pinions H H', and the transmitting-wheels ou arms F FA, on and around the axle and within drum E, whereby the required number of revolutions is obtained, substantially as described.

2. The spur and bevel-pinions H H and I, mounted on the tubular sleeve' or axle, and operated by means ofthe drum and transmitting-wheels, substantially as described.

3. The secondary arm F', carrying the transmitting-wheel, gearing with the drum and secondary pinion H', for the purpose set forth. v

WM. F. GOODWIN.
